Machine coated a rolls of a farmer

Compared with the traditional method, the roll cake machine produces 10 - 20 times higher productivity. Roll making is the profession that brings the main income of Thanh Luong trade village (Bich Hoa commune, Thanh Oai district, Ha Tay province).

To make 1 quintal of roll cake to the market, the worker must 'hug' the hot, hot oven, inhale poisonous gas for hours. As an adult from the village, farmer Bui Do Hau made a cake coating machine that reduced the workers' hardship.

At the end of grade 7, Bui Do Hau had to stay with his mother to do family economy and attend a short-term mechanical class. In 1977, he went to the army and when he returned to his home town, he continued his traditional job of his homeland: coated rolls. Directly working, understanding suffering, Mr. Hau is determined to find ways to improve the sweat of the workers pouring down.

Once heard that in China people grind flour by machine, Mr. Hau explored and he knew that the main part of the machine was two chopped boards, so he was determined to implement the idea of ​​making this grinder. Without money to buy equipment, he took all bank mortgage papers to borrow 10 million dong. However, with little mechanical knowledge, the first grinder failed. When I first ran the test, 1 ton of his rice flour became . pig feed!

After 2 years of breaking down and doing it again, Mr. Hau just let the oven come out . Having a blender, Mr. Hau thought about making a roll cake machine for high productivity. This time, the equipment was constantly broken, so not only money but also furniture in Hau's house also in turn . left. A lot of people for Mr. Hau are 'fans', crazy for going to do this weird thing. But he was not sad but was determined to continue his creativity. After many tests, he found that the cause of the failure was due to the weak motor and the boiler not holding the steam. Later, he found a Japanese motor with a capacity of 100 W and a good boiler cooking system instead.

Contribute to food hygiene control

Mr. Hau's initiative brings many benefits for those who make rolls. This is a machine that can do many things, achieving requirements such as simple operation, high productivity for centralized production, which will contribute to creating conditions for hygiene control in the process. Cake processing.

In 1995, Mr. Hau's first automatic roll coating machine was completed with a capacity of 1 quintal of rolls / hour. If compared with the traditional way, the roll-coated machine gives 10 - 20 times more productivity. Not only has the outstanding productivity, the rollers are coated with the machine, but the quality is better than that of hand-painted because when the machine is coated, the ingredients are kneaded evenly and thoroughly. Faster time should keep the hotness of the cake.

Soon after, many households who made rolls in the village set him up for similar machines. Up to now, most of the baking households in Thanh Luong village have applied Hau's automatic roll coating machine to produce. Not only serving the people working in Bich Hoa commune, the wheel rolling machine . made by Mr. Hau's family has been present in many provinces and cities in the country. And recently, there are also some overseas Vietnamese in the country to put him into making vermicelli making machines, rolls to bring abroad to produce.

Mr. Hau said that he is continuing to research and improve this technology, his desire for invention can be extended to the villages of making vermicelli, rolls, and rice paper that can be used.
